Develop a Secure Network – A Case Study

Abstract: In recent years, so many networks are being built and some of the organizations are able to provide security to their networks. The performance of a network depends on the amount of security implemented on the network without compromising the network capabilities. For building a secure network, administrators should know all the possible attacks and their mitigation techniques and should perform risk analysis to find the risks involved in designing the network. And they must also know how to design security policies for implement the network and to educate the employees, to protect the organization’s information. The goal behind this case-study is to build a campus network which can sustain from reconnaissance attacks. This thesis describes all the network attacks and explores their mitigation techniques. This will help an administrator to be prepared for the coming attacks. This thesis explains how to perform risk analysis and the two different ways to perform risk analysis. It also describes the importance of security policies and how security policies are designed in real world.
